What style of guitar are you interested in? If it's acoustic fingerpicking, you really can't beat Stefan Grossman, plus he was a member of the Fugs, and one of the "Blues Mafia"
Check out the
Guitar Workshop Series I've had good success with Grossman's beginners' stuff, and a little luck with Ernie Hawkins' Willie McTell DVD.
As for Bicycle mechanic video's, I've used the Youtube stuff to supplement
Zinn and the Art of Road Bike Maintenance and
Park's Big Blue Book.
